Beijing and other key cities plan for 10-fold expansion of metro railways

By 2050, mainland cities will have 11,700 kilometres of metro railway, accounting for at least half the world's metro railway, said a bond prospectus of China CNR Corporation, a leading rolling stock manufacturer. This is nearly 10 times the 1,688 kilometres of operating metro railway in 14 cities at the end of 2011.
